 ## Importing Content
 Importing content into a design is one of the most popular use cases. For instance, to add content retrieved from a third-party service or directly from the local hard drive. The following example use cases for implementing this feature. The first function shows how to implement it by adding an image directly from a `blob` object, and the second shows how to implement it by fetching an image via a URL first. Follow the example below to implement this feature, but also be sure to refer to the [related SDK Reference section](https://developer.adobe.com/express/add-ons/docs/references/addonsdk/app-document/#methods) and [code samples](https://developer.adobe.com/express/add-ons/docs/samples/) for more details.
